Abstract
Description
Technical fields:
[0001] This utility model belongs to the field of photovoltaic panel module installation technology, and specifically refers to a photovoltaic panel module pressure block connector. Background technology:
[0002] Photovoltaic (PV) panels are a crucial component of photovoltaic (PV) power plants. The solar cells encapsulated within these panels generate direct current (DC) voltage through the photovoltaic effect, thus producing electricity. PV panels are typically assembled into PV arrays for power generation. Existing PV panels are spliced and installed using clamping connectors.
[0003] Chinese utility model patent (authorization announcement number CN 208353277U, announcement date 2019.01.08) discloses a photovoltaic module mounting block, which includes a block body, bolts, rubber pads, and a top plate. The block body is provided with a first through hole, the rubber pad is provided with a second through hole, and the top plate is provided with a third through hole. The bolt passes through the first through hole and the second through hole in sequence and extends into the interior of the third through hole. The block body is groove-shaped and includes teeth, a first pressing edge, a second pressing edge, and an intermediate connecting part connecting the first pressing edge and the second pressing edge. The first pressing edge and the second pressing edge are respectively located on the upper ends of two photovoltaic module frames that are arranged opposite each other and press the two photovoltaic module frames tightly. The number of teeth is two, which are respectively provided below the first pressing edge and the second pressing edge.
[0004] The aforementioned photovoltaic module mounting blocks have the following defects: when the bolts loosen or a photovoltaic module falls off one side, the main body of the mounting block will tilt towards that side, eventually causing the main body of the mounting block to fail. Summary of the Invention:
[0005] The purpose of this utility model is to provide a photovoltaic panel module clamping block connector that avoids failure of the clamping block when the fasteners loosen or one side of the photovoltaic panel module falls off due to the hooking structure of the main hook and the auxiliary hook.
[0006] This utility model is implemented as follows:
[0007] A photovoltaic panel module clamping connector, comprising:
[0008] A pressure block base includes a base plate and a male end disposed on the base plate, wherein a main hook portion extends obliquely downward from the top of the male end;
[0009] A pressing block, comprising a pressing block body, wherein the upper end of the pressing block body has an upper limit edge extending horizontally to both sides, and the lower end has a female end extending downward to be inserted into the male end, and the bottom of the female end has a secondary hook extending obliquely upward;
[0010] When the female end and the male end are inserted and mated, the secondary hook is located below the main hook to form a hook structure;
[0011] Fasteners are used to tighten and fix the pressure block base to the pressure block, so that the upper limit edge and the base plate form a bayonet for the photovoltaic panel assembly.
[0012] In the aforementioned photovoltaic panel module clamping block connector, a clamping hoop for holding steel strands is provided below the base plate, and the fastener passes through the clamping block and the clamping block base in sequence before connecting to the clamping hoop.
[0013] In the aforementioned photovoltaic panel module clamping connector, the bottom surface of the upper limit edge is a toothed surface.
[0014] In the aforementioned photovoltaic panel module clamping block connector, the fastener is a bolt assembly, including an external hexagonal bolt and a locking nut. The external hexagonal bolt passes through the clamping block and the clamping block base in sequence and is threadedly connected to the clamping hoop. The locking nut is screwed onto the end of the external hexagonal bolt that extends out of the clamping hoop.
[0015] In the aforementioned photovoltaic panel module clamping connector, the male end includes a pair of parallel and spaced first vertical plates arranged on the upper surface of the base plate, and the top of the first vertical plates is provided with main hooks extending obliquely downwards towards each other.
[0016] In the aforementioned photovoltaic panel module clamping connector, the female end includes a pair of parallel and spaced second vertical plates arranged at intervals on the bottom surface of the clamping block body. The bottom of the second vertical plates is provided with oppositely extending secondary hooks, and the two secondary hooks form an interlocking hook structure that is complementary to the main hook.
[0017] The outstanding advantages of this utility model compared to the prior art are:
[0018] 1. This utility model utilizes the hook-and-loop structure of the main hook and the auxiliary hook, combined with fasteners, to form a bidirectional locking mechanism. This ensures that the photovoltaic panel module is firmly clamped between the base plate and the upper limit edge, effectively resisting external forces such as wind loads and vibrations. Even if the fasteners loosen or one side of the photovoltaic panel module falls off, the hook-and-loop structure of the main hook and the auxiliary hook will prevent the clamping block from failing, thus preventing the photovoltaic panel module on the other side from detaching.
[0019] 2. The clamp of this utility model can simultaneously fix the clamping block and connect the steel strand with the fastener, without the need for additional installation steps, reducing the number of accessories and construction time, and improving installation efficiency.
[0020] 3. This utility model uses a clamp to suspend the steel strand, which can distribute the stress (such as wind load and snow load) of the photovoltaic panel module to the support structure such as the bracket, reduce the local load on the pressure block and the pressure block base, and improve the overall wind pressure resistance and tensile strength.

[0022] Figure 2 This is a diagram showing the usage state of this utility model.

[0024] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —2:
[0025] This utility model provides a photovoltaic panel module clamping block connector, which includes a clamping block base 1 and a clamping block 2. The clamping block base 1 includes a base plate 3 and a male end disposed on the base plate 3. The top of the male end extends obliquely downward with a main hook portion 4. The clamping block 2 includes a clamping block body 5. The upper end of the clamping block body 5 has an upper limit edge 6 extending horizontally to both sides, and the lower end has a female end extending downward to be inserted into the male end. The bottom of the female end extends obliquely upward with a secondary hook portion 7. When the female end and the male end are inserted and engaged, the secondary hook portion 7 is located below the main hook portion 4 to form a hook structure. The clamping block base 1 and the clamping block 2 are tightened and fixed by fasteners, so that the upper limit edge 6 and the base plate 3 form a bayonet 9 for the photovoltaic panel module 8.
[0026] This invention utilizes the hook structure between the main hook 4 and the auxiliary hook 7, along with fasteners, to form a bidirectional locking mechanism. This ensures that the photovoltaic panel assembly 8 is firmly clamped between the base plate 3 and the upper limit edge 6, effectively resisting external forces such as wind loads and vibrations. Even if the fasteners loosen or one side of the photovoltaic panel assembly 8 falls off, the pressure block 2 tilts to one side (the auxiliary hook 7 at that end moves diagonally downwards, and the auxiliary hook 7 at the other end moves diagonally upwards). However, due to the hook structure between the main hook 4 and the auxiliary hook 7, the movement angle of the auxiliary hook 7 at the other end is limited. Therefore, the pressure block 2 will not fail, meaning the photovoltaic panel assembly 8 on the other side will not detach.
[0027] It should be noted that the tilt angle between the main hook 4 and the auxiliary hook 7 can be set according to the actual situation, such as 30°-60°.
[0028] Furthermore, a clamp 11 for holding the steel strand 10 is provided below the base plate 3. The fastener passes through the pressure block 2 and the pressure block base 1 in sequence and then connects to the clamp 11. This structure allows the fastener to simultaneously fix the pressure block and connect the steel strand, eliminating the need for additional installation steps, reducing the number of accessories and construction time, and improving installation efficiency. In addition, by clamping the steel strand 10 with the clamp 11, this utility model can distribute the stress (such as wind load and snow load) on the photovoltaic panel module 8 to the support structure such as the bracket through the steel strand 10, reducing the local load on the pressure block 2 and the pressure block base 1, and improving the overall wind pressure resistance and tensile strength.
[0029] To enhance anti-slip performance and prevent the photovoltaic panel assembly 8 from shifting, the bottom surface of the upper limit edge 6 is a toothed surface.
[0030] It should be noted that the male end includes a pair of parallel and spaced-apart first vertical plates 12 on the upper plane of the base plate 3, with main hook portions 4 extending diagonally downwards at the top of the first vertical plates 12. The female end includes a pair of parallel and spaced-apart second vertical plates 13 on the bottom surface of the pressing block body 5, with secondary hook portions 7 extending diagonally upwards at the bottom of the second vertical plates 13. The two secondary hook portions 7 form an interlocking hook structure complementary to the main hook portions 4. The diagonally upward extension of the secondary hook portions 7 facilitates the insertion of the female end into the male end. After insertion, the two will not separate under the action of the interlocking hook structure of the main hook portions 4 and the secondary hook portions 7.
[0031] Furthermore, as one embodiment of the fastener, the fastener is a bolt assembly, including an external hexagonal bolt 14 and a locking nut 15. The external hexagonal bolt 14 passes sequentially through the pressure block 2 and the pressure block base 1 and is threadedly connected to the clamp 11. The locking nut 15 is screwed onto the end of the external hexagonal bolt 14 that extends out of the clamp 11. Generally, two sets of fasteners are provided. In this invention, threaded holes can be provided on the base plate 3 to facilitate tightening of the pressure block 2 and the pressure block base 1. In this case, to increase the length of the threaded connection, the area on the base plate where the threaded hole is provided can be thickened.
[0032] As another embodiment of the fastener, the fastener may be a U-bolt and a lock nut.
[0033] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
